CheckPlaces is a user-friendly extension for Mozilla Firefox designed to help you manage your bookmarks efficiently. With CheckPlaces, you can easily verify if your favorite websites are still functional, identify duplicate bookmarks, and detect empty folders. Simply click on the icon located in the lower right corner of your browser window and select 'check'. In just a few seconds, the extension will analyze your bookmarks and present the results. You have full control over what to do with any duplicates or non-functional links, allowing you to find replacement websites before deleting broken links. CheckPlaces is particularly useful for users with an extensive collection of bookmarks or those who use Firefox Sync and end up with many duplicates. Optimize your browsing experience and keep your bookmarks organized with CheckPlaces.

CheckPlaces is pretty good! I found a nice local cafe that serves amazing breakfast. I enjoyed my time there. The maps are easy to use too, just minor bugs sometimes.
